Series 626 & 628 Industrial Pressure Transmitter

Complete Offering of Ranges, Connections and Outputs

The Series 626 Pressure Transmitters possess a highly precise 0.25% full scale accuracy piezo-resistive sensor contained in a compact, rugged, NEMA 4X stainless steel general purpose housing or cast aluminum conduit housing.

The Dwyer Series 628 Pressure Transmitters are ideal for OEM's with 1% full scale accuracy sensors. The transmitter is also available in the general purpose stainless steel housing and the cast aluminum conduit housing.

The corrosion resistant 316L stainless steel wetted parts allow the Series 626 and 628 transmitters to measure the pressure in a multitude of processes from hydraulic oils to chemicals. The Series 626 and 628 are available in absolute and pressure ranges with a variety of optional outputs, process connections and electrical terminations to allow you to select the right transmitter for your application.

Questions

Question
I need to protect a pressure transmitter from power surges and spikes. The model of the transmitter is: 626-09-GH-P1-E1-S1
Answer
If you are worried about power surges and spikes, we recommend that you use a regulated power supply in your system. See our Model BPS-005 low cost DC regulated power supply.
